05 E55 AMG, high STFT bank 2 (14-22) & bank 1 (4-8) at no load crusing, 2500-3000 RPM. Both B1 & B2 are normal at idle 0 +-.While in park, STFT climbs at 3000 RPM (no vac leak?), When I create a vac leak-nothing changes. After 25-35 miles of mixed driving, LTFT will reach 25 & throw code P2085. All new components = MAF, 550cc Bosch injectors, Bosch upstream O2 sensors, Magnaflow Hi-flow cats, coolant
temp. sensor, SL 55 fuel pump, Bosch high flow fuel filter, intake gaskets…etc…
All coil packs are good, 52psi at fuel rail w/ASI 1:1 ratio adj. regulator (new diaphragm), 93 octane gas, clean “paper” air filters, etc..
I’m at a loss as to what’s causing the issue, I could use some fresh ideas….
